Wall Tie Replacement - Cem-Ties

Replacing Corroded Wall Ties

Wall Tie Replacement is required if the existing wall ties have become corroded leading to cracked and bulging walls. New self tapping helical ties are inserted which pin the two layers of masonry together across the wall cavity.

The drill holes are then filled with coloured mortar to match the existing brickwork. The result is a seamless fix involving no disruption or destructive structural fixing. The helical dry fix tiles can also be used to pin arches above doors and windows which are structurally unsound.

Crack Stitching

Structural Repair of Vertical Wall Cracks

Crack Stitching is used to fix vertical cracks in structurally unsound walls. The process involves cutting out the mortar bed and inserting a helical bar horizontally across the crack. The helical bar is grouted into place.

This process is repeated along the length of the crack. Coloured mortar is used to match the colour of the brick work. The result is a structurally sound repair hardly visible to the naked eye. This method of crack stitching involves little disruption when compared to other more destructive methods.

Bow-Ties

Structural Lateral Restraint using Bow-Ties

Bow-Ties are a lateral restraint system used to stop structurally suspect walls from moving laterally. This method involves drilling a stainless steel pin through the outside wall and screwing it through the joists in the floor.

The masonry around the bow-tie is then injected with tri-set resin until the hole is filled. The outer wall can then be made good with coloured grout. The resulting structurally repair is almost invisible, involves no lifting of floor boards, and causes very little disruption and visual disturbance.

Underpinning >>

Building Subsidence

Repairing the Causes of Subsidence

Subsidence in buildings occurs when the ground on which the foundations are built becomes unstable, allowing movement. The solution is to stabilise the ground preventing further movement.

Once the ground has been stabilised and the subsidence has stopped remedial repairs to the building can take place. Subsidence can be stopped by underpinning the foundations however in some cases simply removing surrounding trees is enough to stabilise the ground.

Brickwork Repointing

Structural Fault Prevention by Repointing

Cement Beds and mortar between brickwork can decay over time - leading to substantial structural damage through constant freezing and thawing and salt deposition

YourLondonBuilders.co.uk has the expertise to ensure that the materials used for repointing will match in terms of compressive strength, permeability, thermal expansion and colour. The techniques used vary from gun point injection to hand repointing.

Rising Damp Treatment

Stopping Rising Damp

To stop rising damp a Damp Proof Course need to installed in the problem walls. There are a variety of ways to achieve this and YourLondonBuilders.co.uk will select the most suitable method for your situation

YourLondonBuilders.co.uk generally use a silicon based chemical damp proof course (the Wykamol pressure injection system) which is inserted into the brickwork. Mortar Injection Systems are also available. Both these systems adhere to BS 6576

Concrete/Stone Repair

Structural Concrete Repair

Concrete degrades overtime - Even modern structures such as tunnels, bridges and high rise blocks, built to stringent specifications, deteriorate due to increasingly harsh environmental conditions.

YourLondonBuilders.co.uk have advanced concrete repair solutions which will restore structural integrity offering protection against freeze and thaw damage, water penetration, attack by chloride compounds and carbonation.

Lintel Repair and Replacement

Fixing Door and Window Lintels

YourLondonBuilders.co.uk use one of two methods to fix failing lintels and archways. The first is traditional replacement - supporting the surrounding brick work and removing the lintel or arch.

The second is to use a Helfix Masonry Beam and Helfix Cem-Ties. This system takes the loading away from the arch. and spreads it to the sides. The advantages are that there is no lengthy disruptive work with projects often taking less than a day to complete.
